摘要:
干树金矿床位于豫西著名的熊耳山矿集区，近年来开展了一系列勘查及科研工作，深部找矿取得重大突破。总结了深部矿体发现过程：热液矿床的成因理论及流体力学理论分析→浅部矿体形态的成因分析→深部矿体预测→工程验证。分析认为，断裂带内含多条矿化蚀变带或矿脉时，处于断裂带底板的矿化蚀变带或矿脉找矿潜力远大于其他矿脉；有矿部位断裂带顶底板蚀变强于无矿部位，构造膨大部位相对于闭合部位更易于成矿。建立了矿床尺度的含矿流体运移成矿模式，为区域深部找矿提供了科学依据。

Abstract:
Ganshu Gold Deposit is located in the famous Xiongershan ore concentration area.In recent years,a series of exploration and scientific research work has been carried out,and a major breakthrough in deep prospecting has been made.The discovery process of deep ore body is summarized:the theory of hydrothermal deposits genesis and the theoretical analysis of fluid mechanics→the cause analysis of shallow ore body morphology→deep ore body prediction→engineering verification.According to the analysis,when there are many mineralized alteration zones or veins in the fault zone,the prospecting potential of the mineralized alteration zone or vein in the fault zone is much greater than that of other veins; In the mine site,the alteration is stronger in the roof and floor of the fault zone in the ore-hosting part than the part without ores.The structurally enlarged part is easier to mineralize than the closed part.The mineral-bearing fluid migration and metallogenic model of the ore scale is established,providing scientific basis for regional deep prospecting.
